The invention discloses a bogie and a rail engineering vehicle, and relates to the technical field of rail vehicles. The bogie comprises a supporting assembly, a damping assembly and a locking assembly. Wherein the supporting assembly comprises a framework and at least two wheel pairs, and the wheel pairs are rotationally arranged at the bottom of the framework; the shock absorption assembly comprises at least two shock absorbers which are transversely arranged, the shock absorbers are oppositely arranged on the two sides of the framework, one end of each shock absorber is connected with the framework through a spherical hinge, and the other end of each shock absorber is connected with the vehicle body through a spherical hinge. The locking assembly comprises at least four supporting pieces and at least two tensioning pieces, the supporting pieces and the tensioning pieces are telescopic and are arranged on the framework in the vertical direction of the damping assembly, the bottom ends of the supporting pieces are opposite to axle boxes connected with the wheel pairs, two of the supporting pieces are used for locking or unlocking one wheel pair, and the tensioning pieces are oppositely arranged on the two sides of the framework. The bottom end of the tensioning piece is rotationally connected with the framework, and the top end of the tensioning piece is rotationally connected with the vehicle body. The bogie not only can keep stable during high-speed operation, but also has low-speed operation capability.

    本发明公开了一种转向架及轨道工程车辆,涉及轨道车辆技术领域。转向架包括支撑组件、减震组件和锁定组件。其中,支撑组件包括构架和至少两个轮对,轮对转动设于构架的底部;减震组件包括至少两个横向设置的减震器,各减震器相对设于构架的两侧,且减震器的一端通过球铰连接构架,减震器的另一端通过球铰连接车体;锁定组件包括至少四个支撑件和至少两个拉紧件,支撑件和拉紧件均可伸缩且沿减震组件的垂向设于构架,支撑件的底端与轮对所连轴箱相对设置,其中两个支撑件用于锁定或解锁一个轮对,各拉紧件相对设于构架的两侧,且拉紧件的底端转动连接构架,拉紧件的顶端转动连接车体。该转向架既可以在高速运行时保持稳定,又兼具低速作业能力。
